Biggest Hole in the Ground
The places on the photos is 2000 ft (700m) deep hole in the ground.
It’s called Korkinsk Coal Mine – the deepest and largest in Europe open coal mine and second largest in the world.
Miles of rails, hundreds of electro trains and giant excavators work in this place.
That’s probably one of the biggest hand made things on the Earth.
